Q345C carbon steel plate sheet steel sheet/carbon steel plate

GJB/1496A-2000 this standard uses and manufactures 28Cr2Mo steel plates with thicknesses of 10, 12, 15, 20, 25, 30mm for armored vehicles, and 26SiMnMo steel plates with thicknesses of 5, 6, 8, 10, 12, 15, 20mm and thicknesses. 28Cr2Mo is armored bullet-proof steel, code-named GY4. It is the main protective device on the tank. It needs to have high elasticity resistance. It also needs to have good processing technology and welding performance to meet the requirements of the tank manufacturing industry.

With the increase of temperature, the yield limit of Q345C carbon steel plate sheet will decrease monotonically, but the tensile strength of Q345C carbon steel plate sheet will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of Q345C carbon steel plate sheet. Near the blue brittleness temperature, the Q345C carbon steel plate sheet strength increases and the plasticity decreases. The elongation and section shrinkage of Q345C carbon steel plate sheet increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.

In addition to quality assurance, service is also important for the competition of steel suppliers. All the after-sales service personnel of the company have received professional training and assessment. The steel products supplied by our company enjoy the life-long quality problem replacement service. In the process of using our steel Q345C carbon steel plate sheet products, if there is any problem, just contact us in time, and our after-sales service personnel will look for countermeasures and solve the problem with you as soon as possible.
